Keywords: high-speed rolling stock, margin of bogie stability, anti-hunting mechanism, high-frequency impedance, track-shift force, stability robustness.

This paper shows how to improve the safety stability margin of high-speed rolling stock based on the absorbing-band anti-hunting mechanism. In comparison with the over-damped anti-hunting mechanisms, it is indicated that the track-shift force can be reduced considerably with the anti-hunting high-frequency impedance being increased moderately. Through examples, it is demonstrated that the technical advantages of anti-hunting soft-attachment have been validated sufficiently in engineering applications. The optimal configuration of anti-hunting dampers is achieved further with the corresponding economical velocity of (350 380) km/h, so that the stability robustness can be emphasized more for the Chinese HSR operation of 300 km/h running.
